About FinEngine Calculator
From the official readme · v1.0.0Description
Standard JavaScript floating-point calculations suffer from IEEE-754 binary representation drift (0.1 + 0.2 === 0.30000000000000004). In multi-year loan schedules, this drift compounds across monthly periods, leaving non-zero terminal balances.
FinEngine Loan Calculator introduces academic-grade, deterministic financial mathematics into the WordPress ecosystem.
Key Features:
* Zero Float Drift Guarantee: Actuarial reducing-balance calculations with strict integer sub-unit Poisha scaling.
* Terminal Reconciliation Rule: Mathematical boundary enforcement guaranteeing the closing principal balance liquidates cleanly to exactly 0.00.
* South Asian Numbering Conventions: Native support for Lakh and Crore formatting (2,45,87,500.00) for Bangladeshi Taka (BDT) and Indian Rupee (INR).
* Full-Site Editing (Gutenberg) Block: Modern WordPress block with live inspector controls.
* Universal Shortcode: Embed anywhere with [finengine_calculator] (compatible with Elementor, Divi, Beaver Builder, and Classic Editor).
* 100% Client-Side Privacy: Zero server tracking, zero AJAX calls, and no cookies. Customer loan details never leave the browser.
* Academic Backing: Developed by Md Golam Mubasshir Rafi in accordance with CFSBR (Centre for Fintech and Strategic Business Research) computational working papers and archived on CERN Zenodo.
